Half of Sol Type Stars May Be Binary?!

In a new study, astronomers have concluded that half of all sun like stars are in a multiple star system.   This comes from scientists using  the upgraded Karl G. Jansky Very Large Array.   These conclusions from scientists that observed a previously unseen companion star.  

The standing theory as to how such a strange formation could have taken place is that the companion must have occurred as the primary star formed and then fractured into two separate bodies during formation.

John Tobin, of the National Radio Astronomy Observatory stated that:
  • "This fits the theoretical model of companions forming from fragmentation in the disk"
  • The new observations add to a growing body of evidence supporting the disk-fragmentation idea.  This showed that disks are present early in the star formation process, a necessity for binary pairs to form through disk fragmentation.
